The darkness is coming to Wainright, Alaska. A group of frozen bodies are eerily and impossibly arranged at the top of a 40-foot pole so FBI agents Fox Mulder and Dana Scully are called in to investigate. X-Files/ 30 Days of Night brings together two iconic franchises, pitting the government's best supernatural investigators against a horde of parasitic vampires.

It has been a year since the isolated Alaskan town of Barrow's population was decimated by vampires during its annual month long sunset. Riddled with grief over the death of her husband Eben, bound by nightmares and void of all emotions beyond hate and sorrow, Stella Oleson has spent the past months traveling the world, trying to convince others that vampires exist. Met with skepticism and laughter, she is ready to throw in the towel when a group of lost souls offers an incredible opportunity: the chance to exact revenge upon Lilith, the vampire queen responsible for the assault on her sleepy Alaskan town. With nothing remaining to live for, and nothing left to fear, Stella joins their mission and ventures into the uncharted underbelly of Los Angeles where she pushes herself to the most extreme limits to stop the evil from striking again.
